Title: Method for regenerating gold plating solution
Inventor: FUKUDA TAKAYUKI
IPC: C25D21/22
Filed: 1987-03-13
Abstract: PURPOSE:To efficiently regenerate a contaminated gold plating soln. contg. gold in the form of potassium gold cyanide, by treating the plating soln. by an ion exchange method so as to remove metals having adverse effect on a plated film. CONSTITUTION:A plating soln. contg. gold in the form of potassium gold cyanide and contaminated by harmful metals having adverse effect on a plated film is passed through a column packed with a cation exchange resin. An H type highly acidic cation exchange resin is preferably used as the resin. The harmful metals are selectively removed by adsorption on the resin and only gold is practically allowed to flow out. Pure water is further passed through the column to wash the resin and the soln. passed through the column is mixed with the washing water and recovered as a regenerated gold plating soln. Hydrochloric acid is then passed through the column to desorb the metals and to regenerate the resin. The pickling soln. is stored as a gold recovering soln. Thus, the contaminated gold plating soln. is regenerated with minimized loss of gold without exerting unfavorable influence on the plating soln.

Title: Temperature adjusting circuit of heat fixation device
Inventor: KURODA KOUKI
IPC: G05B23/02
Filed: 1982-04-07
Abstract: PURPOSE:To decide disconnection of a temperature sensible element exactly in a short time, by heating in advance the temperature sensible element for controlling a heater temperature of a heat fixation device, before a temperature of a heater rises, and detecting its disconnection. CONSTITUTION:When an electric power source switch 1 is turned on, a triode AC switch 3 is turned on by a signal from a controlling circuit 7, a heater 2 is electrified, and also a switch 23 is turned on by a signal 9 from the controlling circuit 7. As a result, a voltage dividing resistance 22 is short-circuited, and to a thermistor 4, more currents flow comparing with the time when the switch 23 is off. The thermistor 4 generates self-heating, and resistance of the thermistor itself drops. In this case, partial pressure Vth of the thermistor 4 is compared with prescribed voltage V2 by the controlling circuit 7, and when Vth is higher, disconnection of the thermistor 4 is decided,the triode AC switch 3 is turned off by a control signal 8, and electrification to the heater 2 is stopped. In this way, disconnection of the thermistor 4 is decided exactly in a short time.

Abstract: PURPOSE:To continuously detect a wide range of an air/fuel ratio with high response and detection accuracy, by calculating an air/fuel ratio on the basis of the output of an oxygen concn. detection means for detecting the oxygen concn. in gas to be measured and slowly changed in its output voltage to the air/fuel ratio and that of an oxygen concn. detection means having the same detection capacity but rapidly changed in its output voltage to the air/fuel ratio. CONSTITUTION:The target voltage Va is subtracted from the output Vs1 of a first oxygen sensor 54 by a differential amplifier DF1 and the difference output DELTAV is imparted to a current supply circuit 63 and a pump current Ip is supplied to the sensor 54 so as to form Vs1=Va to determine the oxygen partial pressure of a measuring space. By detecting the pump current Ip as a voltage signal Vi through a current value detection circuit 64, an air/fuel ratio can be continuously measured. This Vi changes slowly. The output voltage Vs2 of a second sensor part 55 having a high response speed and high detection accuracy is added to Vi through a buffer amplifier 62 to obtain an output signal Vn. By this method, a wide range of an air/fuel ratio is continuously obtained with high response and detection accuracy.

Title: Control timing system
Inventor: OGATA ATSUSHI
IPC: G05B15/02
Filed: 1979-05-14
Abstract: PURPOSE: To decrease the number of the transmission circuits and thus secure the signal transmission in the minimum time, by selecting the operation subject block via the timing pulse given from the generalizing controller and also selecting the unit via the timing pulse composed of the operation subject selecting pulse.  
     CONSTITUTION: Synchronous timing pulse (2) and coded timing pulse (3) to be transmitted serially are produced through timing system 30 and based on clock pulse (1) generated at clock pulse generating circuit 10 and the command given from generalizing controller 20 to be applied to timing systems 11, 12W1N. The application of the identifying pulse of the frames is not required by separating the transmission lines of pulse (2) and pulse (3), and thus only the pulse to identify the control subject block is needed. As a result, each frame can be formed with the minimum pulse, and at the same time the frame space can be minimized. Thus the control subject block selection signal can be transmitted in the minimun time. After receiving pulses (2) and (3), timing system 1i decodes pulse (3) and then transmits timing pulses 1i1W1iM to individual controller (i) to select the control subject unit.

Abstract: PURPOSE:To make available the effective control of engine output, by providing the moving vane at the inlet side of a turbosupercharger and by operating the moving vane correspondingly to engine r.p.m. and engine load. CONSTITUTION:When an engine is running at its r.p.m. C, first and second electromagnetic valves 6, 7 are not energized and so the air is not supplied from an air tank 9 to an actuator cylinder 8. Pistons 13, 14 are displaced in the left direction, a moving vane 17 is rotated in a counterclockwise direction, and a turbine nozzle has its area F3. When the engine r.p.m. is B, a valve 6 operates solely and the air is supplied to a chamber 9, thereby displacing the first piston 13 in the right direction and rotating the moving vane 16 in a clockwise direction. When the engine r.m.p. is A, valves 6, 7 are operated to supply air into chambers 9, 10, causing the moving ring 16 to rotate to its maximum clockwise direction. As a result, an area of turbine nozzle is reduced to its minimum F1.
